A proposal that would require proof of citizenship to register as a Tennessee voter is headed for a full Senate vote.

The measure sponsored by Senate Majority Leader Mark Norris, a Collierville Republican, was unanimously approved Wednesday in the Senate State and Local Government Committee and will now be scheduled for the Senate floor.

The companion bill has been delayed in a House subcommittee until next week.

The proposal would require people seeking to register to vote to document their citizenship with driver’s licenses, passports or birth certificates.

Current state law requires people to check a box on an application affirming under threat of perjury that they are U.S. citizens. Norris has said there’s no way for election officials to challenge that assertion.
